HIGH-STRENGTH WET NONWOVEN FABRIC AND PRODUCTION THEREOF

摘要

PURPOSE:To obtain an extremely soft high-strength wet nonwoven fabric having a strength comparable to that of a filament nonwoven fabric by forming sheets from short fibers having a specific single yarn diameter and fiber length, subjecting the resultant sheets to high-speed fluid treatment and three- dimensionally entangling the fibers therein so as to provide the average distance between the fiber entangled points with a specific length or below. CONSTITUTION:Short fibers having 7-25mum diameter of single yarns and 0.8X10<3> to 2.0X10<3> ratio (L/D) of the fiber length (L) to the single yarn diameter (D) are used to form sheets by a sheet forming method. The resultant sheets are then subjected to high-speed fluid treatment to mutually and three-dimensionally entangle the short fibers constituting the sheets and provide <=300mum average distance between fiber entangled points.
